Pay-Per-Use vs Annual Rental: Water Billing Models Compared
The water industry has two main billing models: pay-per-use and annual rental. They differ significantly in billing logic, cash flow, and user experience. This article compares them to help water businesses choose, with reference to the Water Rental Solution and Water IoT Solution.
1. Two Billing Models
- Pay-per-use: Users top up water volume; the system deducts by actual production-pay for what you use
- Annual rental: Users pay a fixed annual rent for unlimited use within the year
2. Comparison
| Dimension | Pay-per-use | Annual rental |
|---|---|---|
| Billing logic | Deduct by actual volume | Fixed annual fee, unlimited |
| Cash flow | Flows in with top-ups, dispersed | One-time/installment, concentrated |
| User threshold | Low, pay on demand | Higher, prepaid |
| Asset risk | Stickiness depends on usage | Locks long-term use |
| IoT support | Volume stats + auto-deduct | Expiry reminder + one-click lock |
| Fit | Home, commercial direct drinking | Commercial, institutional long-term |
3. Pay-Per-Use Characteristics
- Pros: Low user threshold, pay on demand, continuous cash flow
- Cons: Revenue fluctuates, stickiness depends on usage
- IoT support: Volume stats for precise deduction, Data Dashboard accounting
- Fit: Home, commercial dispensers, shared deployment
4. Annual Rental Characteristics
- Pros: Concentrated stable revenue, locks long-term users, controllable assets
- Cons: Higher user threshold, prepaid
- IoT support: Expiry reminder + one-click lock securing assets, unlock on renewal
- Fit: Commercial, schools/hospitals, offices-long-term water supply
5. How to Choose
| Scenario | Recommended billing |
|---|---|
| Home, unstable usage | Pay-per-use |
| Commercial direct drinking, shared deployment | Pay-per-use |
| Office, school/hospital long-term supply | Annual rental |
| Lock long-term clients, stable cash flow | Annual rental |
The two can also combine: commercial devices on annual rental with pay-per-use for overage-balancing stability and flexibility.
Pay-per-use and annual rental each have strengths: the former offers low threshold and continuous cash flow; the latter offers stable revenue and long-term lock-in.
